You have a niche market, contacts and knowedge.
You are a specialist photographer in a niche.
It would make a good
side line
Look at the real costs of getting commercially licensed. (I have no idea what it is where you are)
Then get a few jobs as a side line to see if it can break even. Or even just make it an almost free hobby
NOTE it might be worth doing one job for your current employer as a free one. (cue long arguments on this supporting for and against)
However I would do this on the understanding that they *rent* the gear from you. Ie your time, as you are employed by them. they have paid for but the kit they rent.
They should understand this.
This will mean that you have a paid job and an example on your portfolio. Over a few of these it could pay for the costs in the certification/registration etc of the costs in seting up the company (the one your current emplyer rents the gear from) You could then get other jobs for your self.
I was going to suggest that your employer might offer this as a service but they would then buy their own drone for you to operate.... so beware of that trap
Once you are off the ground so to speak you need to think like a business, You will need back up kit, all sorts of bits and pieces. I have seen a "Professional" Wedding Photographer with only one camera and flash gun..... disaster if it fails. Real Pro's have a reasonable amount of back up kit. This is a long term thing.
You do need a plan. A busines plan on where you want to go and how to get there, (not the sort of busines plan the bank wants)
You will get lots of suggestions on here.
BTW The Creative Cloud is irrelevant there are lots of similar tools. As is the actual name/model of thre camera or Drone, Clients generally don't care.
